Subseasonal and seasonal forecasting: recent progress and future prospects
More than two decades ago, seasonal forecasting started as a pilot project at ECMWF. Now it is a corner-stone of climate services. Originally a spin-off from seasonal forecasting, the sub-seasonal range covered the then so-called predictability desert; now it is a key building block of the seamless forecasting strategy, with clear prospects for useful skill gains at week 3 and 4.
Although the predictable processes and predictability drivers differ between the subseasonal and seasonal scales, prediction at these time ranges is a combination of initial and boundary problems. Sub-seasonal and seasonal predictions act as a bridge between weather and climate.
This seminar will review recent advances in our understanding of the predictability at these time scales. It will present current forecasting capabilities, and summarise recent but consolidated findings from numerical experimentation and exploitation of public data bases. It will also provide a perspective of incipient developments related with data exploration, forecast products and predictability drivers, which will shape the future of seamless forecasting systems.
The seminar is part of ECMWF's educational programme and is aimed at young scientists but also more established scientists that want to engage more with subseasonal and seasonal forecasting.

Call for Poster Abstracts
Attendees are invited to submit poster abstracts for display during the Annual Seminar. Posters on the areas of data exploration, skill detection and applications are encouraged.
Abstracts for the posters will be reviewed by the Organising Committee. Submitters will be notified by 12 July whether their poster has been selected or not.
Posters should be standard A0 size (portrait orientation), 841mm (width) x 1189mm (height).

The registration fee is 250 GBP for participants not residing in one of ECMWF's Member or Co-operating states. This includes an ice-breaker, one evening dinner and coffee breaks.
EMS travel award
The European Meteorological Society will sponsor one scientist to attend the seminar in its Young Scientist Travel Awards scheme. The award is to support participation of outstanding students and young scientists at EMS-co-sponsored conferences. The award consists of a financial contribution towards travel expenses.
The deadline for applications is 12 June 2019.
